This document provides information on aluminium composite panels (ACPs). It defines ACPs as panels constructed from two aluminium sheets bonded to a non-aluminium core. ACPs have various advantages such as being aesthetically pleasing, providing insulation, having low weight, and being resistant to heat, pollution, and acids. They can be easily shaped and installed for uses like building facades, signage, and interior cladding. However, joints must be carefully sealed and maintained to prevent issues like those seen in the Grenfell Tower fire. The document outlines various installation techniques and provides examples of famous buildings that use ACP cladding.
